Using RadGridView in as a Hierarchical grid is it possible to bind the initial parent level and then load any other levels on demand as they are being opened by the user? If so, does anyone have sample code on how to make this work? I do not see much in the way of documentation for this in the RadGridView WPF documentation.
With some larger customer datasets our screen is slow at loading all of the data at one time.
Thanks...

Hi David,
Such on demand data loading needs to be implemented manually by defining the needed query. The topic is discussed in greater detail in the Hierarchy Load On Demand With RadGridView and How To: grid hierarchy load on demand using MVVM blog posts. Though they are a bit outdated, you should be able to use a similar approach for meeting your requirement.
I hope you find this helpful.
Have a great weekend, David.

Hello Kefilwe,
In order to get familiar with the approach of defining the columns of RadGridView, please take a look at the Defining Columns article. As for the rows, since the control is a data-bound component, they will correspond to the items that are added to the bound source collection. I encourage you to review the Getting Started article, as it covers the topic in details.
Hope this helps.
